I started having mild headaches last week and seeing spots when I stand up after sitting for a while.  My BP has been near perfect this whole pregnancy. 120/80, 118/74...etc. Now it's 105/63, 95/59, 97/65, 102/63 and 89/57 is the lowest it's been. Everything I've read says BP can decrease towards the end of pregnancy and cause dizziness and fatigue...which are pretty normal as it is. I have an appointment Friday and will ask about it then. Just curious if anyone has experience or is experiencing this.
